Question

why do plants bear fruit?what are plant tissues?

Answer 1

The reason plants bear fruit is because it's a adaptation that allows them to spread their seeds in different locations. Animals, such as birds eat them and then disperse them in their droppings.

You have to be more specific as to your second question of, "what are plant tissues?"
Do you need to know what their made of?
